Abstract
In France, the prevalence of hypertension is higher than 30%. Although treatment guidelines have been well established over the last twenty years, the national blood pressure control rate is below the average of high-income countries. This observational study aimed to describe the antihypertensive prescription behaviours of primary care physicians (PCPs) in France and to assess their compliance with current French guidelines, focusing on three specific prescription issues and their potential repercussions on blood pressure control: treatment initiation, treatment renewal or change and type of triple therapy. Prescription data were retrieved using the IQVIA longitudinal patient database (LPD), which delivers real-world data insights from French primary care electronic medical records (EMR). The average number of prescribed therapeutic agents was 1.9 per patient, with 39.3% monotherapy prescriptions. Treatment initiation represented 7.2% of all antihypertensive prescriptions. At treatment initiation, 22.5% of patients were prescribed dual therapy. The proportion of treatment renewal in the same therapeutic class was 74.3% while the proportion of treatment change was 18.5%. Of these, only 6.3% of patients received an additional therapy. Lastly, 35.7% of triple therapies were consistent with the recommended combinations. In conclusion, this study provides evidence of therapeutic gaps in hypertension management in France. The low blood control rate may be attributed to PCPs' therapeutic inertia and lack of knowledge of treatment guidelines. All stakeholders should commit to rapid corrective action in order to provide patients with the best care.

Background
Left atrial flutters (LAFL) are typically observed in patients with previous ablation lines or surgery in the left atrium (LA). Less frequently, scar-related left atrial anterior wall (LAAW) flutters may occur. Although the presence of low-voltage areas (LVAs, a surrogate of scar) in the LA is considered an arrhythmogenic substrate and a marker of atrial cardiomyopathy, the pathophysiologic factors responsible for its formation remain unclear. We hypothesized that compression of the LAAW by the aortic root could be responsible of LVAs found in the LAAW, and therefore, be the substrate for the development of LAAW flutter.
Purpose
We aimed to describe: 1) the relationship between the aortic root and the presence of LVAs in the LAAW, which is the substrate for reentry; and 2) the clinical and electrophysiological characteristics of LAAW atrial flutter.
Methods
Consecutive patients referred for LAFL ablation between April 2019 and September 2022 in a single center were retrospectively collected. Among 55 patients with LAFL, 10 (18%) demonstrated a macroreentrant circuit with a critical isthmus identified in the LAAW, in the absence of previous ablation lines or surgery, and were included in the analysis. Previous pulmonary vein isolation (PVI) was not an exclusion criterion. All patients underwent a multidetector computerized tomography (MDCT) prior to the procedure and the images were analyzed using ADAS 3DTM imaging platform. Activation mapping was performed in all patients using a multielectrode mapping catheter and CARTO 3 navigation system.
Results
9 of 10 patients were male (mean age 74,3 ± 6,3 years). LA enlargement was present in all patients (48,3 ± 4,7 mm) and the mean aortic root diameter was 34,8 ± 3,4 mm. The mean LAAW flutter cycle length was 293,4 ± 68,3 ms. In 9 of the patients (90%), the LAAW flutter critical isthmus was just behind the aortic root, separated by < 1 mm according to the LA-aortic root fingerprinted isodistance map (mean fingerprinted isodistance area was 5,8 ± 2,5 cm2). The remaining patient had the critical isthmus just below the aortic root, between the area in contact with the latter and the mitral annulus. Furthermore, in all cases, the critical isthmus was immersed in LVAs. All but 1 LAAW flutter terminated during radiofrequency (RF) energy applications and rendered it non-inducible. After a median follow-up of 13,6 months (IQ range 5,3-21,6), 7 patients (70%) remained without recurrences.
Conclusion
In patients with LAAW atrial flutter, the presence of LVAs and the critical isthmus of the tachycardia are mostly circumscribed into small areas immediately behind the aortic root. Knowledge of this close relationship and the use of the isodistance map could be useful when mapping and ablating LAAW flutter, helping to straightforward the ablation procedure.

Abstract
(1) Background: Catheter-directed therapies (CDT) may be considered for selected patients with pulmonary embolism (PE); (2) Methods: Retrospective observational study including all consecutive patients with acute PE undergoing CDT (mechanical or pharmacomechanical) from January 2010 through December 2020. The aim was to evaluate in-hospital and long-term mortality and its predictive factors; (3) Results: We included 63 patients, 43 (68.3%) with high-risk PE. All patients underwent mechanical CDT and, additionally, 27 (43%) underwent catheter-directed thrombolysis. Twelve (19%) patients received failed systemic thrombolysis (ST) prior to CDT, and an inferior vena cava (IVC) filter was inserted in 28 (44.5%) patients. In-hospital PE-related and all-cause mortality rates were 31.7%; 95% CI 20.6-44.7% and 42.9%; 95% CI 30.5-56%, respectively. In multivariate analysis, age > 70 years and previous ST were strongly associated with PE-related and all-cause mortality, while IVC filter insertion during the CDT was associated with lower mortality rates. After a median follow-up of 40 (12-60) months, 11 more patients died (mortality rate of 60.3%; 95% CI 47.2-72.4%). Long-term survival was significantly higher in patients who received an IVC filter; (4) Conclusions: Age > 70 years and failure of previous ST were associated with mortality in acute PE patients treated with CDT. In-hospital and long-term mortality were lower in patients who received IVC filter insertion.

Introduction
Left atrial wall thickness (LAWT) is a determinant of transmural lesion formation during atrial fibrillation (AF) ablation. The utility of ablation index (AI) to dose radiofrequency (RF) delivery for the reduction of AF recurrences has already been proven with a target AI ≥ 400 at the posterior wall and ≥550 at the anterior wall.
Objective
To determine if adapting AI to atrial wall thickness (AWT) is feasible, effective and safe during AF ablation.
Methods
Consecutive patients referred for a first PAF ablation. LAWT 3D-maps were obtained from multidetector computed tomography (MDCT) and integrated into the CARTO navigation system. LAWT maps were semi-automatically computed from the MDCT as the local distance between the LA endo and epicardium and categorized into 1mm-layers and AI was titrated to the LAWT, as follows: Thickness < 1 mm (red): 300; 1-2 mm (yellow): 350; 2-3 mm (green): 400; 3-4 mm (blue): 450; > 4 mm (purple): 450 (Figure). The ablation line was designed in a personalized fashion to avoid thicker regions. All ablation procedures were performed under general anesthesia with a high frequency low-volume ventilation. Primary endpoints were acute efficacy and safety, and freedom from AF recurrences. Follow-up (FU) was scheduled at 1, 3, 6, and every 6 months thereafter.
Results
90 patients [60 (67 %) male, age 58 ± 13 years] were included. Mean LAWT was 1.25 ± 0.62 mm. Mean AI was 366 ± 26 on the right pulmonary veins (RPVs) with a first-pass isolation in 84 (93%) patients and 380 ± 42 on the left pulmonary veins (LPVs) with first-pass in 87 (97%). Procedure time was 59 min [49-66]; RF time 14 min [12,5-16]; fluoroscopy time 0.7 min [0.5-1.4]. No major complication occurred. Eighty-six out of 90 (95.5%) patients were free of recurrence after a mean FU of 11 ± 4 months.
Conclusions
Personalized AF ablation, adapting the AI to LAWT allowed decreasing RF delivery, fluoroscopy and procedure time while obtaining a high rate of first-pass isolation. Lesion durability as estimated by freedom from AF recurrences was as high as in more demanding ablation protocols. Abstract Figure. Personalized protocol and results

Introduction
pulmonary vein isolation (PVI) approach implies unavoidable ablation on the posterior atrial wall which is closely related to the esophagus. PVI may result in several complications.
Objective
the present study aims to analyze the stability of the esophageal position inside the mediastinum at the level of the posterior atrial wall from one procedure to another (Redo group) and during a single procedure (multi-image group).
Methods
the esophageal position was compared in two groups. First, pre-procedural multidetector computerized tomography (MDCTs) of the first PVI and the redo intervention (Redo group) were segmented with ADAS 3D™ software to compare the esophageal position and the atrio-esophageal distance prints (Figure A). Second, three imaging modalities were compared for the same procedure (multi-image group): i) preprocedural MDCT; ii) intraprocedural fluoroscopy obtained with the TEE probe in place in three projections with CARTOUNIVU™ (Biosense Webster); and iii) esophageal fast-anatomical map (FAM) obtained at the end of the procedure (Figure D). Ablation procedures were performed under general anesthesia. Exclusion criteria were unavailability or contraindication to obtain any of the techniques. The 3D correlation of the esophageal position acquired with different techniques, was computed in Matlab using semiautomatic segmentation analysis.
Results
35 patients were analyzed for the Redo group. Mean age 61 ± 10 years, 17 (65%) male, mean LVEF 57 ± 7%, mean LA diameter 43 ± 5 mm, median time since previous ablation (and therefore between MDCT acquisitions) was 6 months (IQR 3-9). Mean atrio-esophageal distance for both MDCTs was 1.2 ± 0.6 mm . The esophageal trajectory as related to the atrial posterior wall was left for 20 (57%) patients, central for 6 (18%) patients, and right for 3 (9%) patients, left-central for 4 (11%) patients, and right-central for 2 (5%) patients. There was a 91 ± 5% correlation on the esophageal position between the first procedure and the redo procedure MDCT. In 3 cases the position was clearly different with a correlation of only 40 ± 22%. The multi-imaging group was composed of 100 patients, mean age 61 ± 10 years, 17 (65%) male, mean LVEF 56 ± 7%, mean LA diameter 39 ± 6 mm. The esophageal trajectory as related to the atrial posterior wall was left for 55 (55%) patients, central for 23 (23%) patients, and right for 9 (9%) patients, left-central for 8 (8%) patients, and right-central for 5 (5%) patients. The correlation between MDCT and CARTOUNIVU™ was 82 ± 10% (Figure B); between MDCT and ESOFAM 80 ± 12% (Figure B); and between ESOFAM and CARTOUNIVU™ 83 ± 15% (Figure C).
Conclusions
There is a high stability of the esophageal position between procedures and from the beginning to the end of procedure. This observation needs to be tested for its clinical utility by designing studies that take into account the esophagus distance print to modulate RF delivery Abstract Figure.

Abstract
Background Febrile neutropaenia (FN) is a very common complication in patients with haematological malignancies and is associated with considerable morbidity and mortality. Broad-spectrum antipseudomonal β-lactam antibiotics (BLA) are routinely used for the treatment of cancer patients with FN. However, the clinical efficacy of BLA may be diminished in these patients because they present with pathophysiological variations that compromise the pharmacokinetic (PK) parameters of these antibiotics. Optimised administration of BLA in prolonged infusions has demonstrated better clinical outcomes in critically ill patients. However, there is a paucity of data on the usefulness of this strategy in patients with FN. The aim of this study is to test the hypothesis that the administration of BLA would be clinically more effective by extended infusion (EI) than by intermittent infusion (II) in haematological patients with FN. Methods A randomised, multicentre, open-label, superiority clinical trial will be performed. Patients with haematological malignancies undergoing chemotherapy or haematopoietic stem-cell transplant and who have FN and receive empirical antibiotic therapy with cefepime, piperacillin-tazobactam or meropenem will be randomised (1:1) to receive the antibiotic by EI (during half the time of the dosing interval) in the study group, or by II (30 min) in the control group. The primary endpoint will be clinical efficacy, defined as defervescence without modifying the antibiotic treatment administered within the first 5 days of therapy. The primary endpoint will be analysed in the intention-to-treat population. The secondary endpoints will be pharmacokinetic/pharmacodynamic (PK/PD) target achievement, bacteraemia clearance, decrease in C-reactive protein, overall (30-day) case-fatality rate, adverse events and development of a population PK model of the BLA studied. Discussion Data on the usefulness of BLA administration in patients with FN are scant. Only three clinical studies addressing this issue have been published thus far, with contradictory results. Moreover, these studies had some methodological flaws that limit the interpretation of their findings. If this randomised, multicentre, phase IV, open-label, superiority clinical trial validates the hypothesis that the administration of BLA is clinically more effective by EI than by II in haematological patients with FN, then the daily routine management of these high-risk patients could be changed to improve their outcomes.

Abstract
Image registration has been proposed as an automatic method for recovering cardiac displacement fields from tagged Magnetic Resonance Imaging (tMRI) sequences. Initially performed as a set of pairwise registrations, these techniques have evolved to the use of 3D+t deformation models, requiring metrics of joint image alignment (JA). However, only linear combinations of cost functions defined with respect to the first frame have been used. In this paper, we have applied k-Nearest Neighbors Graphs (kNNG) estimators of the α-entropy (H(α)) to measure the joint similarity between frames, and to combine the information provided by different cardiac views in an unified metric. Experiments performed on six subjects showed a significantly higher accuracy (p<0.05) with respect to a standard pairwise alignment (PA) approach in terms of mean positional error and variance with respect to manually placed landmarks. The developed method was used to study strains in patients with myocardial infarction, showing a consistency between strain, infarction location, and coronary occlusion. This paper also presents an interesting clinical application of graph-based metric estimators, showing their value for solving practical problems found in medical imaging.

Abstract
Simulated magnetic resonance imaging brain studies have been generated for over a decade. Despite their useful potential, simulated cardiac studies are only emerging. This article focuses on the realistic simulation of cardiac magnetic resonance imaging datasets. The methodology is based on the XCAT phantom, which is modified to increase realism of the simulated images. Modifications include the modeling of trabeculae and papillary muscles based on clinical measurements and published data. To develop and evaluate our approach, the clinical database included 40 patients for anatomical measurements, 10 patients for papillary muscle modeling, and 10 patients for local gray value statistics. The virtual database consisted of 40 digital voxel phantoms. Histograms from different tissues were obtained from the real datasets and compared with histograms of the simulated datasets with the Chi-square dissimilarity metric (χ(2)) and Kullback-Leibler divergence. For the original phantom, χ(2) values averaged 0.65 ± 0.06 and Kullboek-Leibler values averaged 0.69 ± 0.38. For the modified phantom, χ(2) values averaged 0.34 ± 0.12 and Kullboek-Leibler values averaged 0.32 ± 0.15. The proposed approach demonstrated a noticeable improvement of the local appearance of the simulated images with respect to the ones obtained originally.

Abstract
In this study we propose a pipeline for simulation of late gadolinium enhancement images. We used a modified version of the XCAT phantom to improve simulation realism. Modifications included the modeling of trabeculae and papillary muscles, and the increase of sublabels to resemble tissue intensity variability. Magnetic properties for each body tissue were sampled in three settings: from Gaussian distributions, combining Rayleigh-Gaussian distributions, and from Rayleigh distributions. Thirty-two simulated datasets were compared with 32 clinical datasets from infarcted patients. Histograms were obtained for five tissues: lung, pericardium, myocardium, blood and hyper-enhanced area. Real and simulated histograms were compared with the Chi-square dissimilarity metric (χ(2)) and Kullback-Leibler divergence (KL). The generated simulated images look similar to real images according to both metrics. Rayleigh and the Rayleigh-Gaussian models obtained comparable average results (respectively: χ(2)= 0.16 ± 0.12 and 0.18 ± 0.11; KL=0.15 ± 0.17 and 0.16 ± 0.18).

Abstract
Left ventricular hypertrophy (LVH) is a complex cardiac condition mainly identified by the thickening of the myocardial wall. Although most of the contemporary cardiac imaging modalities provide high resolution 3D images, the wall thickness (WT) is still measured within the acquired planes. This way of measurement may introduce an error as cardiac wall is not necessarily orthogonal to the plane. In this study we analyze how different approaches to measure WT can affect an automatic identification of hypertrophy. The compared approaches are: WT measured along surface normal and the one provided by a medial surface. For both approaches we evaluated their ability to identify LVH phenotypes by testing with two classifiers: Transductive Confidence Machine-k Nearest Neighbor (TCM-kNN) and Linear Discriminant Analysis (LDA). Fifty three subjects were included in this study: 18 patients with hypertrophic cardiomyopathy (HCM), 13 patients with hypertensive heart disease (HDD) and 22 sedentary subjects (CG). Medial surface based approach allowed obtaining higher classification accuracy in HDD patients, while normal based approach allowed for higher classification accuracy in HCM patients.

Abstract
A model of provision of primary care is experimented in a Catalan health centre. The model implies more varied roles and greater autonomy to nurses. They are the first contact of the patients coming to the health center. They base their decisions on a Guide for interventions on emergencies. The latter are distributed into 3 groups: (i) the cases which can be dealt with and finalized by the misusing the protocols previously established; (ii) the cases which require immediate care from the nurse, later intervention from the physician and common finalization at the end; (iii) the cases which require immediate intervention from the physician and, if the physician is not available, an evaluation from the nurse in the meanwhile. On 202 patients requesting a consultation on the same day, the data below are obtained:--70% cases have been resolved by the nurse using the Guide--14% cases have been resolved by the nurse after a telephone conversation with the physician--16% have been orientated to the relevant departments. Moreover, the on duty physician has been consulted in 6% The Guide appears therefore extremely useful. However, in the long range, the need for additional training in some specific domains were emerging, and that of constant interchange between physicians and nurses as well.

Abstract
The aim of this study was to assess the effectiveness of endorectal MR imaging in predicting the positive biopsy results in patients with clinically intermediate risk for prostate cancer. We performed a prospective endorectal MR imaging study with 81 patients at intermediate risk to detect prostate cancer between January 1997 and December 1998. Intermediate risk was defined as: prostatic specific antigen (PSA) levels between 4 and 10 ng/ml or PSA levels in the range of 10-20 ng/ml but negative digital rectal examination (DRE) or PSA levels progressively higher (0.75 ng/ml year(-1)). A transrectal sextant biopsy was performed after the endorectal MR exam, and also of the area of suspicion detected by MR imaging. The accuracies were measured, both singly for MR imaging and combined for PSA level and DRE, by calculating the area index of the receiver operating characteristics (ROC) curve. Cancer was detected in 23 patients (28%). Overall sensitivity and specificity of endorectal MRI was 70 and 76%, respectively. Accuracy was 71% estimated from the area under the ROC curve for the total patient group and 84% for the group of patients with PSA level between 10-20 ng/ml. Positive biopsy rate (PBR) was 63% for the group with PSA 10-20 ng/ml and a positive MR imaging, and 15% with a negative MR exam. The PBR was 43% for the group with PSA 4-10 ng/ml and a positive MR study, and 13% with a negative MR imaging examination. We would have avoided 63% of negative biopsies, while missing 30% of cancers for the total group of patients. Endorectal MR imaging was not a sufficient predictor of positive biopsies for patients clinically at intermediate risk for prostate cancer. Although we should not avoid performing systematic biopsies in patients with endorectal MR imaging negative results, as it will miss a significant number of cancers, selected patients with a PSA levels between 10-20 ng/ml or clinical-biopsy disagreement might benefit from endorectal MR imaging.

AIM To compare the results obtained with 99mTc-sestamibi and gated-SPECT (gated SPECT in stress and rest) with 201Tl (stress, redistribution, and 24 hour reinjection SPECT). METHODS Twenty patients underwent two SPECT studies, one with 201Tl and the other with 99mTc-sestamibi. RESULTS Using 201Tl as a reference, 177 segments were considered normal, 31 viable and 32 with myocardial necrosis. The overall concordance with 99mTc-sestamibi was 84.2%. In the subgroup of defects that improved after reinjection of 201Tl, it was much less (45%), even after wall thickness and movement (55%) were analyzed. CONCLUSION The overall concordance between 201Tl scintigraphy compared to 99mTc-sestamibi is acceptable. Correlation is low in the viable segments with 99mTc-sestamibi, even after analyzing the Gated-SPECT.

Abstract
A 32-year-old patient experienced a postoperative acute myopericarditis following laparoscopic surgery for gastro-oesophageal reflux (Toupet's fundoplication). His medical history was unremarkable, apart from controlled arterial hypertension. Peroperative circulation was stable, except a short hypertensive episode at CO2 insufflation, controlled with nicardipine. A myopericarditis occurred at the fourth postoperative hour, with apical and inferior hypokinesia at ventriculography, ST-segment elevation with unremarkable coronary arteriography. The patient was discharged at day seven, with a NSAIDs treatment. Echocardiography three and nine months later postoperatively, showed an apical akinesia and persistence of the ST-segment modification, without clinical symptoms. Complications of laparoscopic fundoplication is either specific to surgery (gastro-oesophageal injury, diaphragmatic injury, mediastinitis, stenosis) or secondary to pneumoperitoneum (pneumothorax, carbon dioxide embolism). In this case, following an apparently uncomplicated laparoscopy and, except a direct cardiac trauma from a laparoscopic instrument, either coronary artery spasm, or pneumopericardium with CO2, or delayed gas embolism, or preoperative "silent" myopericarditis could be the potential cause of this cardiac complication.

Abstract
We assessed the predictive value of 99Tcm-sestamibi gated single photon emission tomography (SPET) for changes in perfusion and functional outcome after an acute myocardial infarction and compared the findings on functional recovery with echocardiography using low-dose dobutamine. Gated 99Tcm-sestamibi SPET and radionuclide angiocardiography were performed in 17 patients 4-10 days after an acute myocardial infarction. Six months later, both isotopic studies and rest-dobutamine echocardiography were performed to assess outcome. Perfusion improved in six of seven severely hypoperfused segments (positive predictive value = 85.7%) that showed wall thickening but not in any of 28 segments (negative predictive value = 100%) without wall thickening. The mean ejection fraction improved from 47.7 to 52.3% (P = 0.018). Furthermore, there was a greater improvement in ejection fraction in the group of patients in whom wall thickening predicted a recovery in perfusion (9.0 vs 3.7%, P = 0.01). A comparison of the assessment of functional recovery between gated SPET and dobutamine echocardiography showed good agreement (81.4%). We conclude that the presence of wall thickening in severely hypoperfused segments on 99Tcm-sestamibi gated SPET is predictive of changes in perfusion and functional recovery after acute myocardial infarction, thus identifying the presence of viable myocardium. In contrast, segments showing hypoperfusion and dysfunction after an acute myocardial infarction probably contain scar tissue only.

Abstract
BACKGROUND AND OBJECTIVES The effectiveness of EMLA eutectic mixture of local anesthetics, (ASTRA Co, France) cream in minor surgery on the penis and its acceptability in unpremedicated outpatients were assessed. METHODS EMLA cream was applied 1 hour before surgery (fremulum plasty, circumcision or dorsal section for phimosis, and condyloma accuminatum) in addition to a subcutaneous infiltration of lidocaine 1%, just before incision in cases of circumcision. Verbal Rating Scale (VSR) was assessed during the surgery and the acceptance 15 days later by a questionnaire. RESULTS Thirty-two patients included. In all of the cases, the application of EMLA cream was sufficient, with the exception of one (fremulum plasty). General anesthesia was used for this patient unable to tolerate the proprioceptive sensations (VRS = 0). In cases of circumcision, the subcutaneous infiltration was not experienced as painful. Eighty-eight percent of patients who answered the questionnaire confirmed that if they had to be reoperated on, they would opt for this technique of anesthesia. CONCLUSION EMLA cream is effective in minor penile surgery in adult patients, and it is associated with subcutaneous infiltration of local anesthetic in the case of circumcision.

Abstract
In human immunodeficiency virus type 1 (HIV-1)-infected adults, the proportion of gp120-free CD4 molecules on the surface of T lymphocytes was measured by double-epitope EIA and expressed as a CD epitope concentration ratio. In 51% of these patients (n=81), CD4 T cells showed a significant decrease (up to 100%) in the accessibility of the CD4 epitope in the D1 domain remained accessible. Of interest, a significant increase in the CD4 gp120 binding site concentration, without a change in T cell counts, was observed within 10 days after initiation of zidovudine treatment. Furthermore, CD4 masking by gp120 was associated with a poor clinical patient status. The assessment of the CD4 epitope concentration ratio is proposed as a surrogate marker of disease progression in HIV-1-infected patients.

Abstract
BACKGROUND Previous studies have suggested that aminophylline improves exercise-induced ischaemia by preventing the redistribution of the coronary flow from ischaemic to non-ischaemic myocardium. The purpose of the study was to assess whether aminophylline improves myocardial perfusion in zones supplied by collateral circulation. METHODS Twenty-three patients with an occluded coronary artery and collateral circulation from a non-diseased vessel underwent two symptom-limited exercise 99mTc-MIBI, single-photon emission computed tomography (SPECT) myocardial scintigraphy experiments, which were preceded by an intravenous infusion of either aminophylline (5 mg/kg over 20 min) or saline solution in a randomized double-blind control procedure. The MIBI SPECT images were analysed by two experienced observers who were blinded to each other's data. RESULTS All patients underwent cardiac catheterization. For 16 patients this was because of stable angina and the remaining eight were post-myocardial infarction patients with a positive exercise test. Aminophylline significantly increased the time to the onset of ischaemia in the 15 patients with a positive exercise test (mean +/- SD, 6.5 +/- 1.9 compared with 5.3 +/- 1.8 min, P < 0.005); and ischaemia occurred at higher rate-pressure product (230 +/- 68 compared with 195 +/- 68 HB x mmHg, P < 0.03). After aminophylline, exercise ST-segment depression was 1.1 +/- 0.5 mV, compared with 1.5 +/- 0.8 mV after placebo (P < 0.01). All patients had perfusion defects that resolved partially or completely in the rest images. The imaging score was significantly lower after aminophylline infusion than after placebo (9.7 +/- 9 compared with 12.1 +/- 10, P < 0.01). CONCLUSIONS Aminophylline significantly delayed the time to onset of exercise-induced ischaemia and improved perfusion in zones supplied by collateral circulation. Aminophylline-like drugs may be useful in the treatment of selected patients with ischaemic heart disease.

Abstract
Three hundred and eighty-one consecutive patients referred to our Nuclear Medicine Service from the Cardiology Department during a period of two years have been studied to evaluate Coronary Artery Disease (CAP) using 99mTc-MIBI single photon emission computed tomography (SPECT). The sensitivity and specificity for detecting CAD in the whole group of patients, referred (n = 161) or not (n = 220) for coronary angiography, were calculated following Diamond's method, and were found to be 87% and 92%, respectively. Diamond's method estimates these values from those obtained in the subset of patients with angiography referral (sensitivity 91% and specificity 85%) and the pattern of SPECT responses of both groups (69% and 52%, respectively). A new segmental score system was used to evaluate the location and extent of CAD in the catheterized group. The sensitivity for detecting individual artery disease was 69% and specificity was 81%. The sensitivity in patients with single, double and triple-vessel disease was 90%, 96% and 89%, respectively. In the subgroup of patients without infarction (n = 66) the sensitivity and specificity were 76% (19/25) and 90% (37/41).

Abstract
The aim of our study was to assess bone mineral density (BMD) in pre-menopausal women with systemic lupus erythematosus (SLE) and the influence of disease activity and use of corticosteroids. Lumbar and femoral BMD were measured in 43 patients with SLE (28 on regular steroid therapy, 15 with recent onset, non-treated) and compared with 43 healthy women matched for age. In addition, 21 SLE patients treated with corticosteroids were followed-up with a mean of 36.6 +/- 12.7 months. BMD was significantly lower in SLE patients with prednisone doses > or = 7.5 mg/day than those of recent onset (lumbar: 1.07 +/- 0.11 vs 1.15 +/- 0.13, P = 0.039; femur: 0.85 +/- 0.13 vs 0.98 +/- 0.21, P = 0.034) and the control group (lumbar: 1.07 +/- 0.11 vs 1.13 +/- 0.10, P = 0.040; femur: 0.85 +/- 0.13 vs 0.93 +/- 0.10, P = 0.028). In addition, 18% of SLE steroid users had osteoporosis. Lumbar and femoral BMD were inversely correlated with the time of treatment and the cumulative doses of prednisone. There were no significant BMD changes during the 3-yr follow-up period. In conclusion, in SLE pre-menopausal patients lumbar and femoral BMD is decreased and related to long-term corticosteroid therapy.

Abstract
Recently, it has been suggested that lateral (LAT) spine bone mass measurements by absorptiometry may be more sensitive for detecting bone loss than the standard anteroposterior (AP) projection. The aim of this study was to evaluate the precision of LAT spine dual-energy X-ray absorptiometry (DEXA) and its diagnostic sensitivity. A group of 1554 subjects with no risk factors that might affect bone metabolism and 185 osteoporotic patients with vertebral fractures were studied. Bone mineral density (BMD) was measured in the lumbar spine (standard AP and LAT projections) and proximal femur with a DEXA absorptiometer. The precision of the measurements was assessed in 15 volunteers. Diagnostic sensitivity was evaluated by the Z-score method. Comparing young people and the elderly, spine bone loss in the latter was similar for AP and LAT projections, when it was evaluated in absolute values (glcm2). However, when it was evaluated in percentage terms, bone loss was about twice as high in the LAT projection. LAT spine BMD correlated significantly with all the other areas assessed. The best correlation was found with the standard AP projection (r = 0.67, P < 0.0001). The precision in the LAT projection was found to be within an acceptable range (1.6% in normal subjects, 2% in osteoporotic patients), even though it was about twice that obtained in the AP projection. Diagnostic sensitivity was also better with the AP projection. It is concluded that LAT spine BMD measurements can be assessed with acceptable precision although it is about twice as high as for AP spine measurements.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Tc-99m galactosyl-neoglycoalbumin (NGA) is a new liver imaging agent that specifically binds to a hepatocyte specific membrane receptor, the hepatic binding protein. Scintigraphy with Tc-99m NGA is a noninvasive method that provides functional images of the liver. This report deals with one case of fulminant hepatic failure in which hepatic scintigraphy with Tc-99m NGA predicted hepatic recovery before clinical and biochemical parameters, being a prognostic index in this patient.

Abstract
Monoclonal 111In antimyosin (AMS) uptake indicates the presence of ongoing myocyte damage. In idiopathic dilated cardiomyopathy (IDC), there is diffuse myocyte damage. We have attempted to find a correlation between AMS uptake and functional myocardial parameters. With this purpose in mind, we studied two groups of subjects: group 1 comprised 19 subjects with IDC and group 2 comprised 6 control subjects. In all subjects, an antimyosin scan was performed. Among the subjects with IDC, two-dimensional echocardiography was carried out to determine the left ventricular ejection fraction (LVEF) and left ventricular dimensions, and a gated blood pool study was undertaken to assess the LVEF at rest and end-diastolic and end-systolic volumes. Three months later, repeat antimyosin scintigraphy and equilibrium gated blood pool were performed on 13 of the patients. The mean heart to lung (H/L) ratio in the IDC subjects was 1.82 +/- 0.25 (range 1.42-2.25), a value significantly higher than that obtained in the controls: 1.41 +/- 0.12 (range 1.26-1.58) (P < 0.001). Linear regression analysis did not find a statistically significant correlation between H/L and gated blood pool or echocardiography measures. No marked changes in ejection fraction and antimyosin uptake were found between baseline and follow-up studies. Subjects with IDC have a high incidence of positive antimyosin scans, but antimyosin uptake is not related to any functional or morphological parameters.

Abstract
Two methods for 3D realignment of activation brain single-photon emission tomographic (SPET) studies are analyzed. The first is based on principal axes transformation (PAT). The second uses the results of the first method as initial values to start a least-squares iterative process (LS) to search for the maximum value of the correlation function. Both methods were tested with simulated and real studies. The results of the PAT method showed a maximum translation error of 0.3 +/- 0.1 pixels and a rotational error of 1.2 +/- 0.7 degrees in a total of 100 runs. For the LS method these errors were 0.2 +/- 0.1 and 0.6 +/- 0.3. The realignment for 34 real studies was assessed by three expert observers. The alignment was found to be satisfactory in all cases for the LS method, and in 18 cases (53%) for the PAT method. From the results we conclude that a combination of both methods allows the accurate realignment of SPET neuroactivation studies.

Abstract
Goniopora lobata and polyphyllia talpina were tested in 10 sheep with a follow-up of 12 months. The reference material was a glass ceramic CAP 42. Different implantation sites are used: craniofacial and orthopaedic. A macro and microscopic postoperative study was performed at 3, 6, 9 and 12 months. The results show: (1) biocompatibility with bone and soft tissues; (2) disappearance, without colonisation, of Goniopora Lobata associated with complete bone regeneration at 12 months and (3) later resorption of polyphyllia talpina with a fibrous colonisation, without osseous transformation. The possibility of using these materials in cranio-maxillo facial surgery is discussed.

Abstract
BACKGROUND A study was performed to analyze the use of reactive material in the periodic follow up of diabetes. Likewise, the use of systems to assess glycemic control by primary care physicians was investigated. METHODS Analysis of the habits of use of reactive material was performed on the diabetic population of Tarragona (548,900 inhabitants) by randomized survey of prescription in 525 patients attended in 12 primary care centers. The estimation of amount was carried out by a counting of the public prescriptions made. Similarly the periodicity and the results of the applications of glucoproteins in the reference laboratories were studied. RESULTS A total of 253 diabetics (48%) were exclusively attended in the centers and 272 (52%) performed some type of home self-analysis; 26 (5%) in urine samples, and 246 (47%) in capillary blood. The estimated mean consumption was of 14 blood sugar strips per patient per month (168 strips/year) and 2.7 glucosuria-glucocetonuria strips (32.4 strips/year). The relative urine/blood ratio was 1/5.2. In 343 cases (65%) some glucoprotein measurement was reported within the last year, 330 (63%) corresponding to glucohemoglobin A1. The mean value was 8.3% (normal: 5-8%). The mean number of applications was 1.6 applications per patient per year. CONCLUSIONS An enormous increase was observed in the amount consumed at the province of reactive material in blood and in the measurement of glucoproteins as the system to assess carbohydrate control in diabetes. A significant reduction was found in the use of reactive strips in urine by the diabetic population.

Abstract
BACKGROUND With the aim of evaluating the real consumption on insulin an analysis of its loss with use in clinical practice was carried out. The influence of this loss was investigated in the calculations of prevalence of diabetes (DM) initiating from the consumption of medication, the presumable repercussion in public health costs and possible alternatives. METHODS Revision and analysis of the recipients used by a group of 58 insulin treated diabetics was carried out during a mean period of one month. The theoretic consumption, real consumption and the mean loss per each injection according to visual accuracy and the system employed were evaluated. A deduction was made of the autonomy by storing of insulin. A previous calculation concerning the prevalence of DM in Tarragona (548,900 inhabitants) according to consumption was corrected and an economic estimation of the loss demonstrated over public health costs of insulin during 1991 was made. RESULTS The mean dose prescribed was 39.7 IU/day supplied in 2.4 injections/patient/day. At 30 days (27-35) 310 recipients were evaluated (115 vials/195 boxes). The mean real dose consumed was 53.3 IU/day and the mean loss per injection was 5.6 (25.5% of all the insulin supplied, 4.5% as remnants at the bottom of the recipient). A greater loss was observed by injection a) in patients with reduced sight (6.4 +/- 7.3 IU/5.5 +/- 4.5; NS) and b) in the users of syringes with dead space (5.8 +/- 4.7) with respect to those using an injector insulin pen (4.4 +/- 2.9; p < 0.01). The autonomy by domiciliary storage of insulin was of 103.7 days/patient (prescribed doses) and 78.6 (real consumption). A total of 7 diabetics (12%) had unused expired recipients. The prevalence of insulin treated DM in Tarragona was estimated as around 4.3-4.8/1,000 (2,360-2,635 inhabitants). The expense of loss was 36 million pesetas/year; 6.4 as depreciated remnants of insulin in the bottom of recipients. CONCLUSIONS There is a great loss of insulin in clinical practice which may be avoidable and which influences the public health costs for diabetes. An adequate educative strategy and system of injection independent of user ability would reduce the costs.
